ModuleNotFoundError: No module named 'sailfish'

When I try to run the example of metric learning, I encountered the following error reports：
ModuleNotFoundError: No module named 'sailfish'

When I run the following command, error appears.
CUDA_VISIBLE_DEVICES=0 python -m torch.distributed.launch --nproc_per_node=1 --master_port=29500 tools/train.py configs/metric_learning/cub_resnet50_jpg.py --work_dir work_dirs/metric_learning/cub/r50 --launcher pytorch --fp16

pip install sailfish

Thank you very much. Because my python version is 3.6, so I couldn't pip before.
